Message:
  1. Targets for stopping and starting the derby server now first check whether derby is already running and acts accordingly, just like stop-tomcat does, with the introduction of a force-stop-derby. 2. Have added a similar check for start-tomcat, so that we can't any longer accidentally run ant start and thereby run two tomcat instances on the same host and port.
